Description

Die Erfindung betrifft eine Klimakammer zur messtechnischen Erfassung des thermischen Komforts in einem Prüfobjekt und für witterungsabhängige Funktionsprüfungen an diesem Prüfobjekt.The invention relates to a climate chamber for metrological detection of the thermal comfort in a test object and for weather-dependent functional tests on this test object.

Prüfobjekte wie z.B. Schienenfahrzeuge werden bei unterschiedlichen klimatischen Bedingungen betrieben. Insbesondere müssen Schienenfahrzeuge ebenso kalte Winternächte mit Temperaturen von bis zu - 40°C und extrem geringer Luftfeuchte wie auch heiße Sommertage mit Temperaturen von z.T. 60°C bei direkter Sonneneinstrahlung und sehr hoher Luftfeuchte ohne Beeinträchtigung ihrer Funktionstüchtigkeit überstehen. Desweiteren muss gewährleistet sein, dass der Komfort und hierbei insbesondere der thermische Komfort für Reisende in den Schienenfahrzeuge zu jeder klimatischen Bedingungen gewährleistet ist.Test objects such as e.g. Rail vehicles are operated under different climatic conditions. In particular, rail vehicles must also cold winter nights with temperatures of up to - 40 ° C and extremely low humidity as well as hot summer days with temperatures of z.T. 60 ° C in direct sunlight and very high humidity without impairing their functionality. Furthermore, it must be ensured that the comfort and in particular the thermal comfort for travelers in the rail vehicles is guaranteed to any climatic conditions.

Aus DE 299 03 255 U1 ist ein Klima-Wind-Kanal bekannt, mit dem die Funktionstüchtigkeit und der thermische Komfort insbesondere von Schienenfahrzeugen überprüft werden kann. Hierbei wird ein Schienenfahrzeug in den Klima-Wind-Kanal gefahren und das Schienenfahrzeug von außen mit dem gewünschten Klima wie Temperatur, Luftfeuchte, Sonnenstrahlung, Windgeschwindigkeit, etc. beaufschlagt.Out DE 299 03 255 U1 is a climatic wind tunnel known, with the functionality and thermal comfort can be checked in particular rail vehicles. Here, a rail vehicle is driven in the air-wind tunnel and the rail vehicle from the outside with the desired climate such as temperature, humidity, solar radiation, wind speed, etc. acted upon.

Nachteil dieser Lösung ist jedoch, dass aufgrund der Größe und Komplexität eines Klima-Wind-Kanals nur wenige Klima-Wind-Kanäle zur Verfügung stehen. Hierdurch ergibt sich als weiterer Nachteil, dass die Überprüfung von Schienenfahrzeugen in einem Klima-Wind-Kanal mit hohen Kosten verbunden ist.Disadvantage of this solution, however, is that due to the size and complexity of a climate-wind channel only a few climatic wind channels are available. This results in a further disadvantage that the review of rail vehicles in a climatic wind tunnel is associated with high costs.

Mobile Klimakammern an sich sind aus dem Stand der Technik hinreichend bekannt.Mobile climate chambers per se are well known from the prior art.

So ist eine Vorrichtung zur Betonnachbehandlung beim Betonieren von Tunnelgewölben bekannt, die als Klimakammer ausgebildet ist ( DE 197 01 861 A1 ). Die Wirkung der Klimakammer ist nach außen auf das Tunnelgewölbe gerichtet. Sie wird von einer fachwerkartigen Tragkonstruktion gestützt und bewegt sich auf Rollen durch den Tunnel.Thus, a device for concrete after-treatment in concreting tunnel vaults is known, which is designed as a climate chamber ( DE 197 01 861 A1 ). The effect of the climatic chamber is directed outwards on the tunnel arch. It is supported by a truss-like support structure and moves on rollers through the tunnel.

Bekannt ist ein mobiler Behälter zum Transportieren und Kompostieren und/oder Trocknen von Abfällen, der als Klimakammer ausgebildet ist ( DE 199 30 223 A1 ). Der Container weist eine Klimaanlage auf, wobei die Luft gekühlt und entfeuchtet wird. Die vordere Wand des Containers kann montiert und demontiert werden, um den Abfall ein- bzw. auszuladen. Diese Wand weist zudem Be- und Entlüftungseinrichtungen auf.A mobile container is known for transporting and composting and / or drying waste, which is designed as a climate chamber ( DE 199 30 223 A1 ). The container has an air conditioner, whereby the air is cooled and dehumidified. The front wall of the container can be assembled and disassembled to load or unload the waste. This wall also has ventilation devices.

Auch DE 35 41 334 A1 beschreibt eine mobile Klimatisierungsvorrichtung, die als beweglicher Container ausgebildet ist.Also DE 35 41 334 A1 describes a mobile air conditioning device, which is designed as a movable container.

Keine dieser mobilen Klimaeinrichtungen ist geeignet, Schienenfahrzeuge einer Funktionsprobe bezüglich stark wechselnder bzw. extremer Klimaeinflüsse zu unterziehen.None of these mobile air conditioning systems is suitable for subjecting railway vehicles to a functional test with regard to strongly changing or extreme climatic influences.

Es ist somit Aufgabe der Erfindung, eine Klimakammer bereitzustellen, mit der eine einfache und kostengünstige Überprüfung von Schienenfahrzeugen gewährleistet wird.It is therefore an object of the invention to provide a climate chamber, with a simple and inexpensive inspection of rail vehicles is guaranteed.

Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Anspruches 1 erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.This object is achieved in connection with the preamble of claim 1 according to the invention by the features specified in claim 1.

Erfindungsgemäß besteht die Klimakammer aus in einem Stützportal angeordneten Dämmelementen, die sich reversibel auf- und wieder abbauen lassen und das Objekt umschließen. Ein Klimagerät bringt Luft in die Klimakammer ein bzw. wälzt Luft in der Klimakammer um, wobei über Wärmetauscher des Klimagerätes, über die die Luft geführt wird, die unterschiedlichen klimatischen Bedingungen eingestellt werden.According to the invention, the climate chamber consists of arranged in a support portal insulation elements that can be reversibly up and dismantle again and enclose the object. An air conditioner introduces air into the climate chamber or circulates air in the climate chamber, whereby the different climatic conditions are set via heat exchangers of the air conditioner over which the air is guided.

Die Dämmelemente werden im Raster des Stützportales zusammengefügt und umschließen das zu untersuchende Objekt derartig, dass es von den Dämmelementen umgeben ist. Der Boden bleibt hierbei insbesondere unverändert, d.h. so wie er vor Zusammenbau der Dämmelemente war.The insulating elements are joined together in the grid of the supporting portal and surround the object to be examined in such a way that it is surrounded by the insulating elements. The soil in this case remains in particular unchanged, i. as he was before assembly of the insulation elements.

Die Klimatisierung erfolgt über die in dieser Klimakammer umgewälzte Luft, wobei die Wärme-/Kälteeinbringung über Wärmetauscher, über die diese Luft geführt wird, erfolgt. Nach Prüfungsende können die Isolierelemente wieder abgebaut und um das nächste Objekt herum aufgebaut werden.Particularly advantageous are commercially available insulating elements, in particular according to claim 3 so-called Styroporschalungssteine or PUR sandwich panels according to claim 4, which according to claim 5 at their outer edges have a tongue and groove connection and with which one erects a thermally insulated room around the test object. This room is air conditioned depending on your needs and thus creates the necessary conditions for climate investigations. The air conditioning takes place via the air circulated in this climate chamber, whereby the heat / cold introduction takes place via heat exchangers, over which this air is led. At the end of the test, the insulating elements can be dismantled and assembled around the next object.

Soll das Objekt in seiner Gesamtheit mit den unterschiedlichen klimatischen Bedingungen beaufschlagt werden, stellt diese ein externes Klimagerät über entsprechend konditionierte Luft ein. Das externe Klimagerät ist hierbei über mindestens eine Zuleitung mit der Klimakammer verbunden.If the object in its entirety is to be exposed to the different climatic conditions, it sets an external air conditioner via appropriately conditioned air. The external air conditioner is in this case connected via at least one supply line with the climatic chamber.

Nach Anspruch 7 kann die Herstellung der für die Prüfung notwendigen Luft-feuchtigkeit in der Klimakammer durch eine Befeuchtung der von der Klimaanlage des Prüfobjektes angesaugten Außenluft vereinfacht werden.According to claim 7, the preparation of the necessary for the test humidity in the air conditioning chamber can be simplified by moistening the sucked in by the air conditioning of the test object outside air.

Bauliche StrukturStructural structure

Die Art und Weise wie die Wände und Decke einer mobilen Klimakammer (2) realisiert werden, bestimmt maßgeblich sowohl die Qualität des Klimas in der Kammer als auch die "Mobilität" der Kammer (leichter Auf- und Abbau) an sich. Zwei Gesichtspunkte sind deshalb von entscheidender Bedeutung für das Konzept:

  • ■ Thermische Isolierung auch unter Berücksichtigung der Wärmeverluste auf Grund von Infiltration durch Undichtheiten sowie
  • ■ Handhabbarkeit der Wand- und Deckenelemente.
The way in which the walls and ceiling of a mobile climatic chamber (2) are realized determines significantly both the quality of the climate in the chamber and the "mobility" of the chamber (easy assembly and disassembly) per se. Two aspects are therefore crucial for the concept:
  • ■ Thermal insulation also taking into account the heat losses due to infiltration by leaks as well
  • ■ Handling of the wall and ceiling elements.

Folgende Variante ist auf Grund ihrer Unempfindlichkeit gegenüber Witterungs- und mechanischen Einflüssen sowie wg. der flexibel verfügbaren Maße die vorteilhafteste:The following variant is due to their insensitivity to weathering and mechanical influences as well as wg. the flexibly available dimensions the most advantageous:

Die als Dämmelemente (3) verwendeten PUR-Sandwichplatten sind auf der Innen- und Außenfläche mit Blech beschichtet. Dazwischen befindet sich zur Dämmung ein Kern aus lsolierschaum. Solche Platten kann man in Breiten bis ca. 1,1 m und nahezu beliebigen Längen erhalten. Der Aufbau einer Wand einer Klimakammer (2) erfolgt durch Aneinanderreihung / Aufmauern solcher Platten bis zur erforderlichen Höhe. An den Plattenstößen erfolgt die Verbindung mittels einer Nut- und Federverbindung. Abgestützt wird solch eine Wand mittels einer Stahlkonstruktion, die sich periodisch alle 5 m wiederholt. Die Decke wird analog aus den gleichen Elementen aufgebaut und liegt an der Traufe und am First auf der Stahlkonstruktion auf. Bei einer handelsüblichen Stärke von 10 cm beträgt der Wärmedurchgangswert ca. 0,22 W/(m2K). Ein einzelnes Element mit den Maßen (B x H x T) 1,1 m x 5 m x 0,1 m wiegt ca. 60 kg.The PUR sandwich panels used as insulation elements (3) are coated on the inside and outside with sheet metal. In between there is a core of insulating foam for insulation. Such plates can be obtained in widths up to about 1.1 m and almost any length. The construction of a wall of a climatic chamber (2) is carried out by juxtaposing / walling up such plates to the required height. At the panel joints, the connection is made by means of a tongue and groove connection. Such a wall is supported by a steel structure that repeats periodically every 5 m. The ceiling is constructed analogously from the same elements and rests on the eaves and the ridge on the steel structure. At a standard thickness of 10 cm, the heat transfer value is approx. 0.22 W / (m 2 K). A single element with the dimensions (W x H x D) 1.1 mx 5 mx 0.1 m weighs approx. 60 kg.

Das Figur 1 zeigt den Querschnitt einer mobilen Klimakammer mit Prüfobjekt.FIG. 1 shows the cross section of a mobile climate chamber with a test object.

Diese Konstruktion besteht aus einem sich alle 5 m wiederholenden Stahlportal, das wiederum aus drei zusammenschraubbaren Einzelteilen besteht. Dieses Stahlportal wird im Betonboden verankert. Die PUR-Sandwichplatten der Wände und des Dachs werden mittels Halteprofilen an diesen Stahlportalen fixiert. An einer Stirnwand befindet sich ein durchfahrbares Tor, an der anderen Stirnwand eine ca. 2x2 m große Türe.This construction consists of a steel portal that repeats every 5 m, which in turn consists of three parts which can be screwed together. This steel portal is anchored in the concrete floor. The PUR sandwich panels of the walls and the roof are fixed to the steel gantries by means of retaining profiles. On one end wall there is a passable gate, on the other end wall an approximately 2x2 m large door.

Kälte- und HeizleistungCooling and heating power

Die Durchführung von Klimakomfortprüfungen in einer mobilen Klimakammer (2) soll unabhängig von den am Aufstellort herrschenden, äußeren klimatischen Bedingungen möglich sein. Für die Berechnung der Kälte- bzw. der Heizleistung in der mobilen Klimakammer (2) ist es daher erforderlich, für diese klimatischen Bedingungen die jeweiligen Extremwerte für die Außentemperatur anzunehmen. Das heißt, für den Kühlbetrieb der mobilen Klimakammer (2) ist die höchste anzunehmende Außentemperatur und für den Heizbetrieb die niedrigste Außentemperatur heranzuziehen.The implementation of climate comfort tests in a mobile climate chamber (2) should be possible regardless of the prevailing at the site, external climatic conditions. For the calculation of the cooling or heating power in the mobile climate chamber (2), it is therefore necessary to assume the respective extreme values for the outside temperature for these climatic conditions. That is, for the cooling operation of the mobile climate chamber (2), the highest external temperature to be assumed and for the heating operation, the lowest outside temperature is used.

Für den Kühlfall der Kammer (Heizfall des Zuges) wird dabei der Wärmeeintrag durch den zu prüfenden Zug konservativ zu 40 kW angesetzt. Für den Heizfall der Kammer (Kühlfall des Zuges) wird dabei konservativ ein Wärmeeintrag von 0 kW angesetzt. Als Ergebnis dieser Berechnung ergeben sich die in Tabelle 1 gezeigten Werte für die benötigte Kälte- und Heizleistung. Tabelle 1: Benötigte Kälte- und Heizleistung bei extremen Außenbedingungen Kammertemperatur in °C Außentemperatur in °C Kälteleistung in kW Heizleistung in kW -20 30 65 - 40 -10 - 40 For the cooling case of the chamber (heating of the train) while the heat input through the train to be tested is conservatively set to 40 kW. For the heating of the chamber (cooling of the train) while conservatively a heat input of 0 kW is set. As a result of this calculation, the values shown in Table 1 for the required cooling and heating capacity result. <b> Table 1: </ b> Required cooling and heating capacity in extreme outdoor conditions Chamber temperature in ° C Outside temperature in ° C Cooling capacity in kW Heating power in kW -20 30 65 - 40 -10 - 40

Die in Tabelle 1 ausgewiesene Heiz- bzw. Kälteleistung ist für die Aufrechterhaltung der benötigten Kammertemperaturen notwendig (stationärer Betrieb). Diese Leistungen sind jedoch normalerweise bei akzeptablen Zeiten für den Anfahrvorgang nicht ausreichend. Deshalb wurde eine vereinfachte, dynamische Berechnung durchgeführt. Beispielhaft wurden der Abkühlvorgang von +20°C auf -10°C (bei einer Außentemperatur von +30°C) sowie der Aufheizvorgang von 10°C auf 40°C (bei einer Außentemperatur von -10°C) numerisch simuliert. Als Eingangsparameter dienten die Angaben aus Anlage 1 "Heizbetrieb" bzw. "Kühlbetrieb". Die installierte Kälteleistung wurde mit 65 kW bei einer Temperaturdifferenz von 5 K über dem Wärmetauscher angesetzt. Die installierte Heizleistung wurde zu 40 kW angesetzt.The heating or cooling capacity shown in Table 1 is necessary to maintain the required chamber temperatures (steady-state operation). However, these services are usually not sufficient at acceptable times for the startup process. Therefore, a simplified, dynamic calculation was performed. By way of example, the cooling process was simulated numerically from + 20 ° C to -10 ° C (at an external temperature of + 30 ° C) and the heating process from 10 ° C to 40 ° C (at an external temperature of -10 ° C). The information given in Appendix 1 "Heating mode" or "Cooling mode" served as input parameters. The installed cooling capacity was 65 kW set at a temperature difference of 5 K above the heat exchanger. The installed heating capacity was set at 40 kW.

Das verwendete Rechenprogramm berücksichtigt die Dämpfungseffekte der vorhandenen Wärmekapazitäten (Betonboden, Wagenmasse). Sie vernachlässigt durch den Wagen eingebrachte Wärme- bzw. Heizlasten.The computer program used takes into account the damping effects of the available heat capacities (concrete floor, carriage mass). She neglected by the car introduced heat or heating loads.

Für das Kühlszenario (Bild 2a) war nach ca. 10 Stunden die Solltemperatur von -10°C erreicht. Für das Heizszenario (Bild 2b) war nach ca. 13 Stunden die Solltemperatur von 40°C erreicht.For the cooling scenario (Fig. 2a) the set temperature of -10 ° C was reached after approx. 10 hours. For the heating scenario (Fig. 2b) the set temperature of 40 ° C was reached after approx. 13 hours.

Bei in der mobilen Klimakammer (2) installierten Kühl- und Heizleistungen von 65 kW bzw. 40 kW wären die in den Eisenbahnklimanormen DIN EN 13129 [1] und DIN EN 14750 [2], Test Level 2 geforderten Prüfabläufe ca. zur Hälfte, der Test Level 1 der DIN EN 14750 [2] zur Gänze leistbar. Ebenfalls wäre es möglich, k-Wert-Messungen (auch gefordert in DIN EN 13129 [1] und DIN EN 14750 [2]) durchzuführen.With cooling and heating capacities of 65 kW and 40 kW installed in the mobile climate chamber (2), the test procedures required in the railway climate standards DIN EN 13129 [1] and DIN EN 14750 [2], test level 2, would be approx Test level 1 of DIN EN 14750 [2] completely affordable. It would also be possible to carry out k-value measurements (also required in DIN EN 13129 [1] and DIN EN 14750 [2]).

KlimatisierungAir conditioning

Bei der Bereitstellung des Klimas in einer mobilen Klimakammer (2) sind folgende Problemstellungen genauer zu betrachten:

  • ■ Befeuchtung bei hohen Kammertemperaturen,
  • ■ Entfeuchtung bei Kammertemperaturen unter 0°C,
  • ■ Temperaturverteilung/Luftführung in der Kammer.
When providing the climate in a mobile climate chamber (2), the following problems should be considered more closely:
  • ■ humidification at high chamber temperatures,
  • ■ dehumidification at chamber temperatures below 0 ° C,
  • ■ Temperature distribution / air flow in the chamber.

Befeuchtung bei hohen KammertemperaturenHumidification at high chamber temperatures

Um eine mobilen Klimakammer (2) unter realistischen Bedingungen zu testen, ist es erforderlich, dass bei Kammertemperaturen über 20°C die von der Anlage angesaugte Außenluft befeuchtet wird. Bei stationären Klimakammern wird üblicherweise das gesamte Kammervolumen befeuchtet. In einer mobilen Klimakammer (2) ist jedoch mit höheren Infiltrationsluftwechseln zu rechnen, so dass es schwierig erscheint abzuschätzen, wie hoch die Menge des zu verdampfenden Wassers wegen dieser eindringenden Luftmenge ist. Als wirtschaftliche Alternative bietet sich die Konditionierung lediglich der von der Klimaanlage (4) angesaugten Luft an. Dies hätte zwei Vorteile: Zum einen würde lediglich die tatsächlich notwendige Menge an Luft befeuchtet, zum zweiten ist dieses Problem wesentlich einfacher rechnerisch zu erfassen, zu dimensionieren und zu realisieren. Die Klimaanlage (4) erhält die Luft also aus einem an der Außenluftansaugung zusätzlich angebrachten Kanal, in dem die isotherme Luftbefeuchtung (7) durch Verdampfung erfolgt. Zum Ausgleich der durch diesen zusätzlichen Kanal eingebrachten Druckverluste, die die Klimaanlage (4) beeinflussen würden, ist zusätzlich noch ein regelbarer Stützlüfter notwendig.In order to test a mobile climate chamber (2) under realistic conditions, it is necessary that at room temperatures above 20 ° C, the outside air drawn in by the system is humidified. In stationary climate chambers usually the entire chamber volume is moistened. In a mobile climate chamber (2), however, higher infiltration air changes are to be expected, so that it seems difficult to estimate how high the amount of water to be evaporated because of this penetrating air flow. As an economical alternative, the conditioning only offers the air sucked in by the air conditioning system (4). This would have two advantages: Firstly, only the amount of air actually required would be moistened; secondly, this problem would be much easier to computationally record, dimension and realize. The air conditioning system (4) receives the air thus from a additionally attached to the Außenluftansaugung channel in which the isothermal humidification (7) takes place by evaporation. To compensate for the introduced through this additional channel pressure losses that would affect the air conditioning (4), in addition a controllable support fan is necessary.

Das Problem der Befeuchtung bei hohen Kammertemperaturen kann also relativ einfach durch Befeuchtung der vom Prüfling angesaugten Außenluft umgangen werden.The problem of moistening at high chamber temperatures can thus be circumvented relatively easily by moistening the outside air sucked in by the test object.

Entfeuchtung bei Kammertemperaturen unter 0°CDehumidification at chamber temperatures below 0 ° C

Bei Kammertemperaturen unter 0°C kommt es am Wärmetauscher normalerweise zur Kondensation und zum anschließenden Ausfrieren der Luftfeuchtigkeit. Trifft man keine Gegenmaßnahmen, wachsen die Lamellen des Wärmetauschers mit Eis zu und die Luft kann ihn nicht mehr durchströmen. Im Extremfall kann durch Frostsprengung auch eine Zerstörung des Wärmetauschers eintreten.At chamber temperatures below 0 ° C, the heat exchanger usually condenses and subsequently freezes the humidity. If no countermeasures are taken, the fins of the heat exchanger grow with ice and the air can no longer flow through it. In extreme cases, frost damage can also damage the heat exchanger.

Es bieten sich zwei Lösungswege dieses Problems an:

  1. 1. Die Kammerluft wird mittels Adsorptionsmaterialien derart getrocknet, dass am Wärmetauscher keine Taupunktunterschreitung mehr eintritt. Solche Adsorptionssysteme arbeiten kontinuierlich, indem ein Teil der umgewälzten Luft über ein hygroskopisches Material geleitet wird. Dies adsorbiert einen Teil der Luftfeuchtigkeit und wird an einer anderen Stelle des Gerätes trockengeheizt. Danach wird es wieder der Kammerluft zugeführt.
  2. 2. Das Klimagerät (4) besitzt eine so genannte Abtauautomatik des Wärmetauschers. In diesem Fall wird bei Gefahr des Zueisens für kurze Zeit die Temperatur der durchströmenden Flüssigkeit über den Gefrierpunkt erhöht und es kommt zum Abtauen des Eises. Unter der Voraussetzung dass die Klimakarnmerwände nicht besonders undicht sind, würde so auch eine nachhaltige Trocknung der Kammerluft eintreten, so dass nach einer gewissen Zeit auch keine große Beeinträchtigung durch kurzzeitige Temperaturerhöhungen eintreten würde.
There are two possible solutions to this problem:
  1. 1. The chamber air is dried by means of adsorption materials such that no dew point undershoot occurs at the heat exchanger. Such adsorption systems operate continuously by passing a portion of the recirculated air over a hygroscopic material. This adsorbs a portion of the humidity and is dry-heated at another location of the unit. Thereafter, it is returned to the chamber air.
  2. 2. The air conditioner (4) has a so-called automatic defrost of the heat exchanger. In this case, if there is a risk of breakage, the temperature of the liquid flowing over the freezing point is increased for a short time and defrosting of the ice occurs. Under the condition that the climate chamber walls are not particularly leaky, so would a sustainable drying of the chamber air occur, so that after a certain time, no great impairment would occur by short-term increases in temperature.

Auch bei diesem Problemfeld bieten sich also Lösungen an, um eine anforderungsgerechte mobile Klimakammer (2) zu realisieren.So even in this problem area so solutions offer to realize a requirement-based mobile climate chamber (2).

Temperaturverteilung/Luftführung in der KammerTemperature distribution / air flow in the chamber

Um eine genügend homogene Temperatunrerteilung in der Kammer zu erreichen, ist es erforderlich, den umgewälzten Luftvolumenstrom deutlich über das für diese Kälte-/Heizleistungen übliche Maß zu erhöhen. Bei einem Luftvolumenstrom von 50000 m3/h ergäbe sich über dem Wärmetauscher lediglich eine Temperaturdifferenz von ca. 2 K, wenn eine Kammertemperatur von -10°C herrscht. Bei einem Kammerquerschnitt von - 30 m2 und einem Querschnitt des Prüfobjekts von 10 m2 ergäbe sich im Spalt zwischen Wagen und Kammerwand eine Windgeschwindigkeit von ca. 3 km/h.In order to achieve a sufficiently homogeneous Temperatunrerteilung in the chamber, it is necessary to increase the circulated air flow significantly above the usual for this cooling / heating capacity level. At a volumetric flow rate of 50000 m 3 / h, only a temperature difference of about 2 K would result over the heat exchanger if a chamber temperature of -10 ° C. prevails. With a chamber cross-section of -30 m 2 and a cross-section of the test object of 10 m 2, a wind speed of approximately 3 km / h would result in the gap between the carriage and the chamber wall.

Die Art der Luftführung in der mobilen Klimakammer (2) ist in Figur 3 schematisch dargestellt. Die Luftführung beeinflusst naturgemäß die Qualität der Temperaturverteilung im Prüfraum. Prinzipiell wurde eine Durchströmung längs des Schienenfahrzeugs (1) angestrebt, weil dies zum einen dem Fahrtwind in der Realität am nächsten kommt und zum Anderen so auch inhomogen eingebrachte Warmluft am besten durchmischt wird.The type of air flow in the mobile climate chamber (2) is shown schematically in Figure 3. The air flow naturally influences the quality of the temperature distribution in the test room. In principle, a flow along the rail vehicle (1) was sought, because on the one hand, the wind in reality comes closest to reality and on the other so inhomogeneously introduced warm air is best mixed.

Der an einer Stirnwand befindliche Klima-/Luftbehandlungsgerät (4) befördert über ein einfaches Kanalsystem die behandelte Luft ans andere Ende der mobilen Klimakammer (2). Die Luft strömt im Umluftprinzip am Prüfobjekt (1) entlang und zurück zum Lüfter.The air conditioning / air treatment device (4) located on an end wall conveys the treated air to the other end of the mobile climatic chamber (2) via a simple channel system. The air flows in the circulating air principle along the test object (1) and back to the fan.
